Hemorrhoids

Definition

Hemorrhoids are swollen blood vessels in and around the anus and lower rectum. They stretch under pressure and are similar to varicose veins in the legs. Hemorrhoids are either internal or external.

Internal hemorrhoids develop inside the anus. They are painless and sometimes bleed a lot during bowel movements. They may also protrude during bowel movements. If they protrude from the anal opening and cannot be pushed back, they can cause severe pain.

External hemorrhoids
develop under the skin around the anus and can easily be felt or seen as a lump. They bleed when broken by straining, rubbing, or scratching.

Symptoms

In most cases, symptoms will go away within several days. Although many people have hemorrhoids, not all experience symptoms.

Common symptoms include:

Bleeding from the anus that may appear:

On the stool

On the toilet paper

In the toilet bowl

Anal itching and burning

Swelling and pain during bowel movements

Sensitive lumps of various sizes around the anus

Bleeding from the rectum or blood in the stool can be a symptom of other diseases involving gastrointestinal tract or colon/rectal cancer. It is important to see a doctor if you have any rectal bleeding.

Diagnosis

You will be asked about your symptoms and medical history. A physical exam will be done. Your anus and rectum will be examined to look for swollen blood vessels. A digital rectal exam will be done. This is done by inserting a gloved, lubricated finger into the rectum to feel for abnormalities. Sometimes, it is necessary to do the exam with the use of an endoscope that allows the rectal canal and other parts of the colon to be viewed.

Treatment

Initial Treatments

Sitz baths—sitting in plain, warm water 2-3 times a day for about 10 minutes each time

Ice packs—putting cold packs on the anus for short periods of time to relieve pain and swelling

Medication—applying hemorrhoidal creams or suppositories to the affected area

High-fiber diet
—eating more fresh fruit, raw or cooked vegetables, and whole grains has been shown to reduce hemorrhoid symptoms

Fluids—drinking plenty of non-alcoholic fluids will help soften stools

Nonsurgical Procedures

If these treatments do not provide relief, one of several nonsurgical procedures may be used to shrink or destroy the hemorrhoidal tissue. These procedures, which are generally performed in a doctor’s office, include:

Rubber band ligation
—a rubber band is placed around the base of the hemorrhoid to cut off circulation and force the hemorrhoid to wither away within a few days

Sclerotherapy—a chemical solution is injected near the blood vessel to cause scarring and shrinkage of the hemorrhoid

Coagulation therapy—electricity, laser, or infrared light is used to shrink the hemorrhoidal tissue

Surgery

If nonsurgical procedures are not an option or fail to resolve the problem, surgery may be needed.

Hemorrhoidectomy
is the permanent removal of hemorrhoids by cutting the hemorrhoidal tissue away. Some of the newest surgical treatments involve using stainless steel staples. While many surgeons favor these treatments, there is some evidence that techniques that are more traditional produce more consistent and long-lasting relief.

Prevention

The best way to prevent hemorrhoids is to keep stools soft so they pass easily. The following practices can help:
